Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 3 generators on 32 points:

(1,2)(3,7)(4,5)(6,8)(9,10,11,14,12,15,16,13)(17,18)(19,25)(20,29)(21,23)(22,27)(24,26)(28,31)(30,32);(2,5)(6,7)(10,13)(11,16)(14,15)(17,19,26,32,21,28,20,27)(18,22,29,31,23,30,24,25);(1,3,4,8)(2,6,5,7)(18,23)(22,30)(24,29)(25,31)
